26 Claims.

My invention relates to machines for applying to articles a coatingof cement, it being of especial utility in connection with work upon which it is desirable to lay a substantial thickness of adh sive along a band of definite width. An eX- ample of such work is furnished by the tops of tennis-shoes, the lower margins of which are to be cemented in preparation for the attachment of insoles.

An object of the invention is to effect the delivery cf an ample quantityo'f the cement under ready control, and to so forward the workfor its coating that the feeding means will not gather the coating-substance, to transfer it to the opposite side of the work from that being coated or to become clogged bysuoh accumulation. To accomplish this purpose, I combine with a cementapplying member feeding means situated below and wholly at one side of the applying member and arranged to engage thework to advance it to said applying member. For the applying means I prefer to employ 2.:I10ZZ1Q, thus insuring a free delivery of "cement. For the feeding means one or more oscillatory members are desirable, there being shown herein ,a plurality of ieeding fingers movable into and outiof engagement with the work, this movement being efiected by actuating means which may consist of eccentrics carried by a rotatable shaft at one side of the nozzle. The eccentrics are, as shown, arranged at different angles about their shaft to produce successive action of the fingers, thus giving a substantially continuous advance of the work. The movable feeding means may co-operatewith an abutment-surface against which the work is pressed, and -I prefer to utilize for this purpose a surface upon the nozzle into co-operation with which the ice-ding fingers movefrom the side opposite the passage-opening of the nozzle. With the cement-applying means and the work-feeding means thus related, any excess delivery or drip of cement will fall clearof thefeeding members and, therefore, will not interfere with their action. As herein disclosed, thisdrip is received by a receptacle beneath the nozzle, at one side of whi h receptacle the feeding means ,is 10- for retaining a portion of said cement. "In the' embodiment oftheinvention which II have chosen 1933, Serial No. 654514 to illustrate, the supply of cement is elevated from a receptacle through a conduit to the nozzle, said nozzle being mounted upon a work-supporting table carried upon the top of the receptacle. The quantity of cement delivered to the nozzle may be varied by a valve-controlled opening in the conduit.

One of a variety of forms which my invention may assume is illustrated in the accompanying drawings. Here, 1 l

. Fig. l is a. vertical section through my im proved cementing machine;

Fig. 2, asection on the line 11-11 of Fig. '1;

Fig. 3, a top plan view of the applying and feeding elements; and

Fig. 4, a partial side elevation of the top or upper of a tennis-shoe which has been operated upon by the apparatus.

At It appears a cement-receptacle having at one side acovered filling spout i 2 andat the bottom a valveddrainage connection M. The receptacle supports upon its top a casing i6 furnishing both a closure for said top and a mounting for the elements of the machine. The upperhorizontal wall iii of the casing serves as a table over which work-pieces are advanced to thecementapplying means and to the means which feeds the pieces automatically into co'operation with the applying means.

' Considering first the means for applying cement to the work, the casing-wall 3 has a boss 29 horizontally bored to receivea spindle 22 rotatable about its axis by a handle 24. Extending throughthe spindle from a point within the boss to the end opposite the handle is apassage 25 (Fig. 2), opening into a nozzle .26 secured to the spindle. The nozzlehas a depending portion 28 extended laterally and having at its lower edge a delivenyslotor opening 35 (Fig. 1). This opening is shown as situated above the open toptl of a drip-receptacle 32 formed in the casing i6 and delivering to the main receptacle ifi .over an inclined bottom wallfid (Fig.2). At the end of the passage 25 withinthe boss is a lateral opening '35 through the spindle,'which, when said spindle is turned by its handle, maybe moved into and out oi registration witha :verticalpassage 38 in the casing-'yvall i8. ThlSIiStO allow or to oheckthe delivery of cementrrom the nozzle.

Toithepassage 38 is connected a pipe or conduit 59 extending into the cement in the receptable HI and joined to the outlet of a rotary pump 42' (Fig. 1) supported upona bracket 44 depending from the casing [6. The rotor of the pump has connected tofit a vertical shaftllfijourn'aled in the casing and geared at 48 to a horizontal shaft 50 turning in the side walls of said casing. To the shaft 50 power may be applied, either intermittently or continuously through any desired driving mechanism, said mechanism not being illustrated. To furnish means for regulating the discharge through the nozzle-opening 30 or to furnish a relief-flow if the nozzle-passage is closed at 36 by the rotation of the spindle 22, the vertical passage 38 (Fig. 2) has leading from it a horizontal passage 52 (Figs. 2 and 3) serving as a bypass and terminating in a discharge-opening 54 (Fig. 1) located above the receptacle Hi. The size of the opening 54 may be varied by a valve 56, and thus the quantity of cement directed to the nozzle by its passages altered to obtain the desired delivery through the nozzle-opening to the work. With the nozzle in the operating position, the passage delivering through the depending portion 28 to the opening 39 is first downwardly inclined at 58 and then is curved upwardly and again down to the opening. The lower wall of the curved portion rises at 62 to substantially the level of the upper wall at the end of the inclined passage 58. Behind the upwardly extending wall 62 is formed a depression in which, when the machine is stopped after an operation upon a piece of work, the cement left to flow by gravity through the nozzle will be retained, that free to drip being the very limited amount just above the opening 30. A torsion-spring 64 surrounds the spindle 22 and normally holds the delivery portion of the nozzle in close proximity to the plane of the work-supporting surface of the table 8 for yieldable co-operation with the feeding mechanism, which will now be described.

The shaft 58 has fast upon it a series of eccentries 56, located in a compartment 61 of the casing l6 extending outside the receptacle In. These eccentrics are shown as arranged in three groups, disposed angularly above the shaft with respect to their maximum eccentricity 120 degrees apart. A set of the eccentrics made up of one of each of the three groups succeed one another side by side and are followed by other sets simi larly disposed. Each eccentric acts upon a finger or feeding member 68 surrounding it, this en-- larged surrounding portion being inclined for ward, in the direction of advance of the work on the table l8, and up, to a work-contact-surface upon its upper edge, this surface preferably being toothed, as appears at 10 in Fig. 1, to furnish effective feeding engagement. All the fingers move in slots in a plate ll (Fig. 2) set in the top of the compartment 61, and may be guided during their movement under the influence of the eccentrics by a single horizontal rod '12, extending between the walls of the casing and of the compartment and passing through inclined openings 14 in said fingers. Thus supported and under the influence of the eccentrics, the surfaces 10 travel in generally oval, inclined paths, up into contact with the work, forward to feed it beneath the nozzle-opening 36, down clear of the Work and then back to the initial position. In this feeding action, the fingers co-operate with an approximately horizontal abutment-surface 16 upon the nozzle at the rear of the opening 30, this surface lying at or slightly above the work-supporting surface of the table I8. Such surface yieldably resists the upward pressure exerted by the fingers against the work, and the work is slid along it in the proper relation to the nozzle-opening to receive cement therefrom. Because of the their eccentrics and the relation to one another of the members of said groups, their feeding effect upon the work may be made continuous, one group coming into action at the time the previously acting group becomes ineffective. By the manner of spacing the fingers, this feeding effect for each group is distributed uniformly across the entire width of the work-area operated upon. It will be seen that the fingers terminate short of the field of action of the nozzle, they, with their actuating mechanism, being wholly at one side of the discharge of cement, so there is no possibility that their action will be interfered with by the drip. With respect to the nozzle and fingers, the work may be correctly located by an edge-gage (Fig. 3) having its shank secured to the top of the table I8 by slot-and-screw connections 82. This allows the application of the band of cement upon different widths or transverse portions of the margin of the work.

To briefly outline the manner of using the machine, the operator, taking a shoe-top T which is to be coated at t with a band of cement, this being turned'inside-out as illustrated in Fig. 4, elevates the nozzle 26 by the handle 24 and lays the work, with its outer side uppermost, upon the table l8 against the edge-gage 80. He thereupon allows the nozzle to be lowered by its spring 64 until the work is pressed yieldably by the nozzle-surface 16 against the toothed edges 10 of the fingers 68. The machine may then be started, and the pump 42 forces cement from the receptacle l0 into the nozzle 26, from which it flows, under the control of the relief or by-pass valve 56, through the opening 30 in a more or less heavy band along the margin of the shoe-top. As advanced by the fingers'in their oscillation, the thus-traveling work isguided by the operator against the edge-gage 89 until its entire margin has been encircled, when the machine is stopped. The supply from the receptacle l0 ceases and the cement which is still in the nozzle is, in the main, held from delivery by the wall 62. The operator then swings up the nozzle by the handle, removes the coated work, and the machine is ready for operation upon another shoe-top. Any flow or drip from the nozzle beyond the edge of the work falls directly into the receptacle 32 and flows back to the source, without possibility of being transferred to the feeding mechanism, which is entirely separated from it laterally, and to the under side of the work. If desired, the apparatus may have the pump and feeding mechanism operated continuously, the closure of the opening 35 by the elevation of the nozzle stopping the delivery of cement.
